<p>The brush element (10) comprises a body component (11) with a cross section substantially shaped like a circular ring and intended by its central aperture (14) to be mountable on a shaft, and a plurality of pin-like members (12) projecting from the body component (11). The pin-like members (12) are wide enough to enable an effect to be achieved which pushes the root crops to be dug in axial direction. At the same time, with a view to obtaining a pin structure with sufficient elasticity, the pin-like members (12) have been formed to be bipartite or nearly bipartite pin-like members. A longitudinal slit (13) of the pin-like members separates the halves of the pin-like members (12), and the halves of the pin-like members (12) are conical of their root portion.</p> |
